HTML Minifier Next 7 Is ESM-Only

HTML Minifier Next 7 is out—and the title gives it away, it drops support for CommonJS and is ESM-only now.

The update includes another breaking though very specific change:

removeStyleLinkTypeAttributes and removeScriptTypeAttributes have been so closely related (in spirit), they were merged into one option, removeDefaultTypeAttributes.

In CommonJS environments on Node.js older than 22, keep using HTML Minifier Next 6—I don’t maintain old versions, but HMN 6 has been regularly updated and is still in good shape (from all I know 🙂).

For the type-related changes, no action is needed if you don’t use either option; preset output is not affected, as both the conservative and the comprehensive preset had the two options enabled.

(The update includes a few more improvements, but these are the two most important ones.)

As always, if you run into any problem (or have an idea for a feature), report it in the HTML Minifier Next repo. Cheers!
